Removing fields

The following Base Employee fields have been removed from their respective collections due to low fill rate adding no value to the dataset.

Removed fields

Data field	Collection
education.date_from_month	Education
education.date_to_month	Education

Removing categories

hidden_details category

The hidden_details category is being removed from the Base Employee schema.

Updates to the data aggregation pipeline now ensure that all necessary information is properly populated in the standard schema fields. As a result, the separate hidden_details identifier has become redundant.

Removed fields

Data field	Data type
hidden_details	Array of objects
hidden_details.hidden_collection	String

Legacy categories

The following legacy categories with nested fields are being removed from all future Base Employee dumps and the dataset schema, as they are no longer actively updated. However, the data is stored in our database and can be requested on demand.

Job title classification updates

Changes

We are improving our job title classification system with refined department and management level categories.

Multi-source Jobs data	department management_level is_decision_maker
Clean Employee data	department management_level

C-Level migration: department → management_level

• The "C-Suite" department has been eliminated (previously 2.3M records).

• C-Level executives are now classified by their functional department (e.g., CFO → Finance & Accounting, CTO → Engineering and Technical), with "C-Level" assigned as their management level.

Reduced "Other" classifications

• The "Other" department has dropped from 8.9M to 2.1M records (76% reduction) as significantly more job titles are now accurately categorized into specific departments.

New category: "General Management"

• A new "General Management" department has been added to capture leadership roles that span multiple functions (4.5M records).

Experience and Education Update

April 21, 2026

Overview

We are releasing an update to the Experience and Education categories in employee data. This release includes schema additions, data quality improvements, and a change to the ordering of active experiences. To apply all changes smoothly, the delivery for this update will be a full reload of both collections.

Added new fields

Clean Employee Data

Adding new data fields to experience category.

Data field	Description	Data type
member_experience[].company_shorthand_name	Shorthand / vanity identifier for the company	String
member_experience[].company_website	Company website URL	String
member_education[].institution_shorthand_name	Shorthand name from the institution profile URL	String

Multi-source Employee Data

Adding new fields to expand information about active experience.

Data field	Description	Data type
active_experience_company_website	Website of the company in the employee's active experience	String
active_experience_company_shorthand_name	Shorthand name of the company in the active experience	String
active_experience_company_logo_url	Logo URL of the company in the active experience	String

Data improvements

1. Data quality improvements

• Stale deleted records removed

Previous mapping logic could classify an experience as active (deleted: 0) even after the record stopped being updated. These records have now been identified and corrected. As a result, you may see a net reduction in deleted: 0 experience counts. This change reflects cleaner, more accurate data, not data loss.

• Improved fill rate on key fields

The updated mapping logic improves coverage on two critical experience fields:

Data field	Improvement
title	Higher fill rate and fewer null values
date_from	Higher fill rate and fewer null values

2. MSED active_experience ordering change

The first entry in the active_experience array will now be ordered by greatest date_from (i.e., most recent active experience first) in the Multi-source Employee Data.

Previously, ordering was based on order_in_profile, which could produce inconsistent results due to the legacy mapping logic. The new ordering is deterministic and reflects the employee's most recent active role.

Action required if you consume active_experience[0]

Verify that your pipeline handles the new ordering correctly. The most recent experience will now always appear first.
